Turbine, rotational energy, and electric generators are the correct answer for the blanks from the given options.
<h3>What is an electric motor?</h3>
An electric motor is a mechanism that turns electricity into mechanical energy.
The interaction between the motor's magnetic field and electric current in a wire winding generates force in the form of torque imparted to the motor's shaft in most electric motors.
An electric generator is physically equivalent to an electric motor, but it converts mechanical energy into electrical energy using a reversed flow of power.
The sentences describe how power generation works as;
All <u>turbines </u>work on the same basic principle of converting kinetic energy, generated through the combustion of fuels or from the movement of wind or water, into <u>rotational energy.</u> This energy is then used to drive an <u>electric generator</u> to produce electricity.
Hence, Turbine, rotational energy, and electric generators are the correct answer for the blanks.

Answer:
Explanation:
The static charges are generated due to excess or deficiency of electrons, because these are the smallest quanta of charge available at the molecular level which can get transferred with minimal energy requirement.
These charges are usually generated by friction between the two surfaces leading to the transfer of electron from one to another.
When a plastic pipe is rubbed with a cloth then due to friction the surface of the cloth loses electron which gets stuck at the surface of the pipe making it negatively charged.
Answer:
An object is accelerating when it.
Explanation:
The potential energy is 4.10 J
Explanation:
The potential energy of a body is given by
where
m is the mass of the object
g is the acceleration of gravity
h is the height of the object relative to the ground
For the lemming in this problem we have
m = 0.078 kg is its mass
h = 5.36 m is the height above the ground
is the acceleration of gravity
Solving the equation,
